   An update that fixes 5 vulnerabilities is now available.

Description:

   This update for X Window System client libraries fixes a class of
   privilege escalation issues.

   A malicious X server could send specially crafted data to X clients, which
   allowed for triggering crashes, or privilege escalation if this
   relationship was untrusted or crossed user or permission level boundaries.

   The following libraries have been fixed:

   libX11:

   - plugged a memory leak (boo#1002991, CVE-2016-7942).
   - insufficient validation of data from the X server can cause
     out of boundary memory read (XGetImage()) or write (XListFonts())
      (boo#1002991, CVE-2016-7942).

   libXi:

   - Integer overflows in libXi can cause out of boundary memory access or
     endless loops (Denial of Service) (boo#1002998, CVE-2016-7945).
   - Insufficient validation of data in libXi can cause out of boundary
     memory access or endless loops (Denial of Service) (boo#1002998,
     CVE-2016-7946).

   libXrandr:

   - Insufficient validation of data from the X server can cause out
     of boundary memory writes (boo#1003000, CVE-2016-7947, CVE-2016-7948).
